Silicone sealants are resistant to fuels such as gasoline and diesel because of their chemical makeup. However, you should ensure that you use a high-quality silicone sealant when working with fuel-resistant applications such as hot oil or grease-resistant applications such as food preparation areas or where there may be a risk of a fire hazard if the sealant should catch fire.

Is silicone sealant resistant to gasoline?
Nothing of the sort — Regardless of the formulation, all silicones will dissolve or break down when exposed to gasoline, regardless of how long they last.
Is silicone safe for fuel?
Is it possible to use your silicone hoses to supply fuel to a vehicle? Is it possible to use silicone hoses for oil or fuel? The short answer is no, because they are porous.
What sealant is resistant to gasoline?
Polysulfide epoxy sealant: polysulfide epoxy is one of the most durable sealants on the market. Because of this, it can also be used in gas stations. An epoxy polysulfide sealant is the strongest gasoline-resistant sealant because of its chemical resistance and strength. Concrete repairs can also be done with it.
Does fuel dissolve silicone?
The product will be damaged by the gasoline. Does gasoline dissolve silicone in this case? Silicone-based products such as Ultra Blue offer good seals and good oil and coolant resistance, but they should not be used in gasoline environments because of the flammability of the silicones involved.
What is the best sealant for gasoline fittings?
Aviation Form-a-gasket Number 3 is the best gasket for gasoline use. Permatex also provides a High Temperature Thread Sealant as an option.
What silicone is good for gas?
Oil pans, axle assemblies, and fuel injectors all benefit from Permatex PermaShield Fuel Resistant Gasket Dressing and Sealant, a polyester urethane sealant that is impervious to gasoline and all other automotive fluids.
Is silicone resistant to diesel fuel?
Using silicone with a diesel fuel tank is a no-no. Gasoline and diesel are not a problem for the Permatex No 2 sealant.
Is RTV silicone fuel resistant?
A variety of applications exist for adhesive sealants in the automotive and aerospace industries. Fuel-resistant RTV silicone, EX3-110, by Exonic, is a superior sealant for fuel-resistant applications.
Will Flex Seal hold up to gasoline?
Neither extreme heat nor pressure can withstand Flex Seal. Is it safe to use on a gas tank? Does Flex Seal have a place in a gasoline tank? No.
Is it OK to use Teflon tape on gasoline fittings?
Aside from gasoline and oil, the chemical inertness of PTFE tape makes it resistant to both. To seal and lubricate fuel line joints, it is commonly used in automotive applications.
